Office Action

§DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. KR10-2022-0039772, filed on 03/30/2022. Claim Objections Claim 1 is objected to because of the following informalities: the claim has two periods, which is not allowed, and the limitation in the parenthesis assigning values x and y should be without parenthesis, for example in a form of wherein clause. Claims 5-7 the steps should have the preposition “the step of” instead of “a step of” as the limitations further limit the steps that were previously introduced. Appropriate correction is required. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of copending Application No. 18859388 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the only difference between the claims is the aluminum alloy series, which are obvious as substantially similar aluminum alloys. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of copending Application No. 18854745 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the only difference between the claims is the aluminum alloy series, which are obvious as substantially similar aluminum alloys. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of copending Application No. 18848811 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the only difference between the claims is the aluminum alloy series, which are obvious as substantially similar aluminum alloys. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Allowable Subject Matter Claims 1-15 are allowable. The following is an examiner’s statement of reasons for allowance: novel and inventive over prior art of record. The closest prior art (Lim et al. US 20150368824 A1) discloses a method of pre-patterning (roughening) aluminum substrate and anodizing the substrate at 10 V to 30 V for about 1-30 minutes and coating the anodized layer with hydrophobic/oleophobic layer comprising PDMS or polymethylhydrosiloxane or others. Hofmeister et al. (US 20130216779 A1) teaches commercially available two-part silicone elastomer kit Sylgard 184 is the most common material used to prepare PDMS. The two parts, base and curer, are usually mixed in 10:1 mass ratio. PDMS mixture is too viscous to fill the nanoholes of the templates, so its viscosity can be reduced by mixing in n-heptane. Kim et al. (Adv. Funct. Mater. 2018, 28, 180019) with supporting information) discloses a method of anodizing aluminum substate by anodization in 0.1M H3PO4 bath for 70 seconds at 195 V, followed by etching (pore widening) in 0.1M H3PO4 bath for 150 min., and further anodization if needed. Kim teaches that anodization increases the anodized layer thickness or pore length and etching increases pore diameter or widens the pores. However, the prior art of record does not disclose nor suggest PDMS comprising the instantly claimed chemical formula 1, together with the anodization parameters as claimed without pre-pattering. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to Wojciech Haske whose telephone number is (571)272-5666.
